Common Mistakes
Confusing fluid ounces with weight ounces.
Fluid oz measures volume; weight oz measures mass; they differ for most ingredients.
Using US cups for metric recipes.
A US cup is 236 mL; a metric cup is 250 mL.
Assuming all ingredients weigh the same per cup.
1 cup of flour (125g) weighs much less than 1 cup of sugar (200g).
